SPECIFICATION forming part of Letters Patent No. 355,823, datedJanuary-11,1887.

Application tiled September 14, ISEF.

To all whom t may concern:

Be it known that l, ALvIN F. JnNKs, of Pawtucket, county of Providence,and State of Rhode Island, have invented an Improvement in Ring-Railsfor Spinning and Twisting Machines, of which the followingdescription,`in connection with the accompanying drawings, is aspecilication, like letters on the drawings representing like parts.

This invention has for its object to improve, and at the same timesimplify and-cheapen, the construction of ringrails for use in spinningand twisting frames, my improved rail, with its attached rings,be inglighter in weight than usual cast-metal flanged rails now commonly made.

Heretofore in the manufacture of spinningmachines great diiiiculty hasbeen experienced in correctly mounting the ring-rail upon the 2olifting-rods, such difficulty arising from the lack of trueparallelismof the holes bored through the rail for the reception of theliftingrods, or from the lifting-rods being out of trueparallelism,owing to fault in their guides.

In practice the ring-rail must be moved uniformly at each end, and mustbe restrained from the possibility of either longitudinal or lateralmovement when in operation, and the lifting-rods must be free to bemoved without 3o binding or cramping in their guides.

In accordance with my invention the ringrail, with 'rings attached, maybe quickly applied to the usual lifting-rods without rereaming` theholes, and the rods may be moved freely. v

My improved rail is composed of two narrow metallic bars securedtogethenfone above the other, by means of screws or bolts and nuts insuch manner as to leave between the said 4o rails a space in which toinsert the ring-holding plates, the latter being` clamped between thesaid bars and extended laterally therefrom, the said plates near theirother ends being supplied with rings. The rings are clamped in the saidrail before it is applied to the frame, and to enable lthe rail, withits attached rings, to be applied to the machine with the rings incorrect position with relation to the spindles, and at the same timeenable the ring-rail to 5o be readily combined with or to be attached toSerial No. 213,516. (No model) the usual lifting-rods, so that thelatter may be moved freely and without any liability of being cramped orbound in their guides, I have provided my improved ring-rail with oneround hole, which will be fitted snugly by one of the lifting-rods,andwith a second hole, oblong in shape and ofl enough greater areaincross-section than the lifting-redes to enable the said lifting-rod toenter it loosely, such construction enabling the ring-rail to be read-6o ily applied to any lifting-rods without reboring the rail orenlarging or rereaining the holes therein.

Providing the ring-rail with one round hole which is a fit for one ofthe lifting-rods,al1 lia- 65 bility of longitudinal movement of the railis obviated, while the oblong or larger hole near the opposite end ofthe rail passes readily down over the other co-operating lifting-rod.

If both of the holes in the rail were a fit to 7o the lifting-rods,therail could not be so quickly applied.

Figure 1,in front elevation, shows part of a spinning-frame,itsliftingrods, and aring-rail applied thereto. Fig. 2, in plan view,broken out to shorten the ligure, shows al ring-rail and attachedholders and rings embodying my invention; Fig. 3,a section in the line.fr of Fig.

2; Fig. at, a modification showinglone ring and holder and part of aring-rail, part of the rail 8o above the holder being broken out; andFig.

5 is a section of Fig. 4 in the dotted line x.

The frameA, rails B B', and lifting-rods C C', having usual bearings,are and may be all as in United States Patent No. 222,330, or of usualconstruction common to ring-spinning frames.

The rings a, herein shown as double rings, but which may be of any usualshape, are forced into or otherwise suitably heldin hold- 9o ers c',composed preferably of sheet-steel, slotted as at 2 2.

The rail is composed of two narrow metal bars, b b, preferably of Tshape in crosssection (see Fig. 3) for sake ot' lightness, the 95 saidbars being firmly clamped together to secure the holders between them byscrews b2, preferably two screws for each holder, the said screws alsopassing through the slots 2 2 in the said holders.

(See Fig. 2.) Instead of roo these screws I may use bolts, as 3, or Imay employ rivets, as 4, in Figs. 4 and 5, they entering holes in theholder.

Each rail has a round hole, c, near one end, which is of a diameter toexactly fit the liftingrod 0,130 which it is to be secured; but near itsother end the said rail is provided with an oblonghole, o', which isenoughlarger than the lifting-rod to' fit over the other lifting-rod, C.without touching it except at its front and rear sides, as shown in Fig.2, in which condition the rail may be connected to the said lifting-rodsby set-screws d d.

The oblong hole c' obviates any reaming or reboring of the rail, oradjustment of the usual bearings for the lifting-rods G C.

A ring-rail such as described, andprovided with holes, as stated, may bereadily applied to the lifting-rods of any spinning-frame ofsubstantially like capacity.

. I do not claim a rail having two round holes or holes of the same areain cross section asA the lifting-rods.

My improved rail may be sold with its rings and ring-holders attached,thus avoiding the trouble in the mill ofsetting and adjusting the ringsseparately after applying the rail to the machine.

I claim- A ring-rail composed of two bars,one above the other, andprovided with one hole, c, to fit one lifting-rod, and with anotherhole, c', of greater area in cross-section than the liftingrod to enterit, combined with a series of platelike ring-holders extended from oneside of the said ring-rail, and with rings held by the said holders,substantially as described.x

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
